I'm trying to get an Archlinux guest running on a Archlinux host. Everything works except ethernet. When I boot the host, --- # dmesg |tail [ 8.265493] Bridge firewalling registered [ 8.514547] IPv6: ADDRCONF(NETDEV_UP): virbr0: link is not ready [ 8.645303] ip6_tables: (C) 2000-2006 Netfilter Core Team --- Then I do --- # virsh -c lxc:/// start gitolite Domain gitolite started # dmesg |tail [ 348.793398] device veth0 entered promiscuous mode [ 348.793553] IPv6: ADDRCONF(NETDEV_UP): veth0: link is not ready [ 348.997973] IPv6: ADDRCONF(NETDEV_CHANGE): veth0: link becomes ready [ 348.997998] virbr0: topology change detected, propagating [ 348.998001] virbr0: port 1(veth0) entered forwarding state [ 348.998008] virbr0: port 1(veth0) entered forwarding state [ 348.998017] IPv6: ADDRCONF(NETDEV_CHANGE): virbr0: link becomes ready [ 349.784174] EXT4-fs (xvdg): re-mounted. Opts: (null) --- Then I enter the guest and do --- # ip link 5: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT qlen 1000 link/ether 02:00:00:00:00:17 brd ff:ff:ff:ff:ff:ff 7: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN mode DEFAULT link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 --- So, eth0 exists. Now, still in the guest: --- # systemctl start dhcpcd@eth0 A dependency job for dhcpcd(a)eth0.service failed.

Even though ip link should a eth0 device, the sys-subsystem-net-devices-eth0.device has failed? I don't understand this. This is libvirt 1.0.1 in linux 2.6.11. I tried with both systemd 197 and (thinking that recent changes with device naming could be the problem) with 196. It didn't work on either. The domain configuration is: --- <domain type='lxc'> <name>gitolite</name> <uuid>3122bf1d-11bb-0dd8-be64-7e352b3f8694</uuid> <memory unit='KiB'>262144</memory> <currentMemory unit='KiB'>262144</currentMemory> <vcpu placement='static'>1</vcpu> <os> <type arch='x86_64'>exe</type> <init>/sbin/init</init> </os> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>restart</on_crash> <devices> <emulator>/usr/lib/libvirt/libvirt_lxc</emulator> <filesystem type='mount' accessmode='passthrough'> <source dir='/mnt/gitolite'/> <target dir='/'/> </filesystem> <interface type='network'> <mac address='02:00:00:00:00:17'/> <source network='default'/> </interface> <console type='pty'> <target type='lxc' port='0'/> </console> </devices> </domain> --- I also tried using bridged networking configuration but I see the same problem. What could be causing this? Any ideas? Thanks, Marco
